nanopb
A small code-size Protocol Buffers implementation in ANSI C for embedded systems and memory-constrained environments.
What is nanopb?
Nanopb is a lightweight implementation of Google's Protocol Buffers designed specifically for embedded systems and memory-constrained environments. It provides efficient data serialization with minimal code footprint, enabling Protocol Buffers communication on microcontrollers and other resource-limited devices. The library maintains compatibility with standard Protocol Buffers while optimizing for small binary sizes.
Embedded systems developers and firmware engineers working with microcontrollers, IoT devices, or any memory-constrained systems that require efficient data serialization and communication protocols.
Developers choose Nanopb over standard Protocol Buffers implementations because it delivers the same serialization capabilities with significantly smaller code size, making Protocol Buffers technology viable for resource-constrained embedded systems where memory optimization is critical.
